Calibrachoa plant named ‘Duealgo’

ABSTRACT

A new and distinct cultivar of  Calibrachoa  plant named ‘Duealgo’, characterized by its compact, outwardly spreading to trailing and decumbent plant habit; freely branching growth habit; early flowering habit; numerous large yellow orange-colored flowers with red-colored centers and venation; and good garden performance.

Botanical designation: Calibrachoa sp.

Cultivar denomination: ‘DUEALGO’.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar ofCalibrachoa plant, botanically known as Calibrachoa sp. and hereinafterreferred to by the name ‘Duealgo’.

The new Calibrachoa plant is a product of a planned breeding programconducted by the Inventor in Rheinberg, Germany. The objective of thebreeding program is to create new uniform Calibrachoa plants with largeattractive flowers.

The new Calibrachoa plant originated from a cross-pollination made bythe Inventor in July, 2008 in Rheinberg, Germany of a proprietaryselection of Calibrachoa sp. identified as code number A05-5410-003, notpatented, as the female, or seed, parent with a proprietary selection ofCalibrachoa sp. identified as code number F-0318-2375, not patented, asthe male, or pollen, parent. The new Calibrachoa plant was discoveredand selected by the Inventor as a single flowering plant from within theprogeny of the stated cross-pollination in a controlled greenhouseenvironment in Rheinberg, Germany in May, 2010.

Asexual reproduction of the new Calibrachoa plant by vegetative terminalcuttings in a controlled greenhouse environment in Rheinberg, Germanysince May, 2010 has shown that the unique features of this newCalibrachoa plant are stable and reproduced true to type in successivegenerations.

SUMMARY OF THE INVENTION

Plants of the new Calibrachoa have not been observed under all possibleenvironmental conditions. The phenotype may vary somewhat withvariations in environmental conditions such as temperature and lightintensity without, however, any variance in genotype.

The following traits have been repeatedly observed and are determined tobe the unique characteristics of ‘Duealgo’. These characteristics incombination distinguish ‘Duealgo’ as a new and distinct Calibrachoaplant:

-   -   1. Compact, outwardly spreading to trailing and decumbent plant        habit.    -   2. Freely branching growth habit.    -   3. Early flowering habit.    -   4. Numerous large yellow orange-colored flowers with red-colored        centers and venation.    -   5. Good garden performance.

The new Calibrachoa can be compared to plants of the female parentselection. Plants of the new Calibrachoa differ primarily from plants ofthe female parent selection in flower color as plants of the femaleparent selection have orange-colored flowers.

The new Calibrachoa can be compared to plants of the male parentselection. Plants of the new Calibrachoa differ primarily from plants ofthe male parent selection in flower size as plants of the newCalibrachoa have larger flowers than plants of the male parentselection.

Plants of the new Calibrachoa can be compared to plants of Calibrachoa‘KLECA016120’, disclosed in U.S. Plant Pat. No. 19,488. In side-by-sidecomparisons, plants of the new Calibrachoa differed primarily fromplants of ‘KLECA016120’ in the following characteristics:

-   -   1. Plants of the new Calibrachoa were more compact than plants        of ‘KLECA016120’.    -   2. Plants of the new Calibrachoa had thicker stems than plants        of ‘KLECA016120’.    -   3. Plants of the new Calibrachoa had larger and darker        green-colored leaves than plants of ‘KLECA016120’.    -   4. Plants of the new Calibrachoa had larger flowers than plants        of ‘KLECA016120’.    -   5. Plants of the new Calibrachoa and ‘KLECA016120’ differed        slightly in flower color.

DETAILED BOTANICAL DESCRIPTION

The aforementioned photograph and following observations, measurementsand values describe plants grown during the summer in 10.5-cm containersin a glass-covered greenhouse in Rheinberg, Germany under commercialCalibrachoa production practices. During the production of the plants,day and night temperatures averaged 18° C. and light levels averaged4,500 lux. Rooted young plants were pinched one time three weeks afterplanting and were 13 weeks old when the photograph and description weretaken. In the following description, color references are made to TheRoyal Horticultural Society Colour Chart, 1995 Edition, except wheregeneral terms of ordinary dictionary significance are used.
